Peru LNG Overview

• 1st LNG plant in South America

• Commissioned in June, 2010

• 4.4 MTPA Capacity

• Gas is supplied from Repsol YPF and Petrobras

developed fields near the Camisea fields via a 34-

inch (860 mm) supply pipeline runs 408 kilometres

• The LNG plant is operated by Peru LNG which is a

consortium of Hunt Oil Company (50%), SK Energy

(20%), Shell (20%), and Marubeni (10%)

LNG Loading Arm – A Complex & Critical Asset

Business Challenge – Time is

• Loading Arm issue resolution delayed due to:– No Limit switch status in any HMI

– Limited field data in the HMI including limit switches

– Distance between loading arm and instrument maintenance shop

– Different descriptors in DCS and PLC/HMI for same failures

– Very difficult to troubleshoot and resolve issues in a timely manner

5

Inability to quickly resolve loading arm issues

resulted in over 700 hrs downtime/yr (~2%)

resulting in increased demerge cost and lost

capacity equating to over $1M/yr

Results and Benefits• Deduced LNG Carrier demurrage

• Reduced LNG Loading arm downtime by >700 hrs/yr

• Increased LNG loading capacity by >2%

• Improved overall plant utilization

• Annual savings are estimated to be >$1MM/yr

22

Leveraging the PI System to solve this business

challenge is illustrative of the “art of the possible”

and value now, value over time

© Copyr i gh t 2014 O SIs o f t , LLC .

• Reduced loading arm

downtime by >2% resulting in:

– Decreased LNG carrier

demurrage

– Increase LNG loading

utilization and capacity

– Annual savings >$1MM/yr

Solution Results and Benefits

When Loading LNG, Time is Money

Business Challenge

• Inability to quickly

troubleshoot LNG loading arm

issues due to lack of data and

information in context led to:

– Increased demurrage

– Decreased LNG loading &

plant capacity

• Use the PI System to

integrate, normalize,

analyze, visualize, and

notify enabling a proactive,

efficient approach to LNG

loading arm issues

“Using the PI System to integrate, normalize, analyze,

visualize and notify instrument alarms and related information

on 4 LNG loading arms reduced downtime, demerge costs,

and increased LNG loading capacity by over 2% resulting in

annual savings >$1M/yr”.
